Hertel 1000615 Turning Insert CPMT21505LF HC210

Product Description

The HERTEL 1000615 is a solid carbide turning insert with a TiN coating applied via PVD process, designed for external turning operations on CNC and manual lathes. Identified by insert style CPMT21505LF and manufacturer grade HC210, this insert features an 80-degree diamond shape with a neutral hand orientation and an 11-degree relief angle. The corner radius measures 0.0079 inches, the inscribed circle is 0.25 inches, and the insert length is 6.45 mm (0.2539 inches). It is screw-held and suited for precision turning where consistent edge geometry and coating durability are required. Machinists and CNC operators working with stainless steel, nonferrous, and superalloy materials are the primary users.

This insert is intended for turning applications on workpiece material groups M (stainless steel), N (nonferrous), and S (superalloys and heat-resistant alloys), with secondary suitability for group K (cast iron). The CPMT style and T chip breaker geometry make it applicable to light finishing and semi-finishing passes in production turning environments. The HC210 grade with PVD TiN coating provides wear resistance suited to moderate cutting speeds and interrupted cuts across these material groups.

Installation Notes

This insert is installed and replaced by machinists or tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque screwdriver for the screw-clamp holding system to avoid seat damage or insert fracture. Inspect the toolholder seat and shim for wear or debris before seating a new insert.
